Forged Steel Insulated Flanged Ball Valve

Zhejiang Chenxiang Valve Co., Ltd. offers the forged steel insulated flanged ball valve for viscous media applications. This product solves a common industry problem. In asphalt production, resin synthesis, sulfur transport, waxy oil, and high-viscosity chemical pipelines, media often cool and solidify. This solidification causes valve blockage. Our product has an external jacket on the standard valve body. This jacket circulates steam or thermal oil. The continuous heat circulation maintains the process temperature. This design prevents solidification from the start. The product serves petroleum, chemical, metallurgy, and power industries. It works for compressed air, natural gas, coal gas, LPG, nitrogen, oxygen, hydrogen, steam, flue gas, and various process tail gases. Our models include BQ41F, BQ47F, BQ47Y, and BQ47PEEK.

The product uses body materials such as A105, F304, F316L, LF2, F11, F22, F53, F55, 4A, 5A, Inconel, Monel, 2205, 2507, 904L, copper alloy, titanium alloy, Hastelloy, and nickel alloy. You can choose manual, worm gear, pneumatic, electric, or hydraulic drives. Connections come in RF, FM, and RTJ. The structure is floating ball or trunnion ball. Trunnion types meet DIB-1 and DIB-2 standards. Our owner has over 20 years of valve industry experience. He deeply understands the technical challenges in chemical and heavy oil industries. Our factory uses CNC sawing machines, CNC lathes, and CNC machining centers. We have a submersible pressure tester. This tester simulates underwater conditions to check sealing performance. Every forged steel insulated flanged ball valve gets ultrasonic cleaning before shipment. This process removes internal chips and oil. Our direct-reading spectrometer checks materials to prevent mix-ups.

We support OEM and ODM for our product. We provide a 1-year warranty. Our after-sales team can offer remote guidance for installation and commissioning. Each valve comes with a complete material report, pressure test report, and CE certificate. Payment terms are 30% advance for regular products and 50% for custom orders. Trade terms are EXW and FOB. We accept USD, EUR, and other currencies. Choose our forged steel insulated flanged ball valve to eliminate solidification problems in your viscous media pipelines.
